Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison

We use pellon. If you are asking about how we set a job up. We first print our outline color with registration marks on a pellon, then we take a piece of film positive unprinted spray a little adhesive on it and lay it on the pellon, no we can register all screens to this and test print on the film one color at a time, and you can wipe it off if you need to adjust your registration. We use that same piece of film for weeks. Then when we have it all ready to go we test on a reject shirt. Reduces the need to find a shirt to test on.
